To further explore the model (REF ) at small (but finite) \(t\)  one may switch to canonical variables at \(t\ne 0\) , as we did in the toy example in eqs. (REF ), (REF ), and study this model and its properties. No such analysis of the possible discontinuity between the models (REF ) and (REF ), or between their supergravity generalizations, was performed in [1]}, and the issue of the Kähler metric singularity in the UV limit presented in eq. (REF ) was never raised. This issue requires a new detailed investigation, which is the goal of our paper.
